Fish (initial weight: 25.0 ± 1.0 g) were stocked at 120 individuals per hapa (1 × 1 × 1.75 m³) in triplicate groups, with 12 hapas per system and reared for 70 days. The water quality parameters (temperature, 27.5–30°C; dissolved oxygen, 6.50 mg/L; pH, 6.8–7.5) remained within the optimal range for tilapia production across both systems. GIANT strain reared in IPRS exhibited 1.38% day⁻¹ higher (<i>P</i> &lt; 0.05) specific growth rate, and survival rate SR was 18.32% higher (<i>P</i> &lt; 0.05) compared to Kafr El Sheikh strain. Similarly, GIANT tilapia achieved in IPRS exhibited 4.26% higher crude protein compared to RW, while crude fat was significantly lower in IPRS (<i>P</i> ≤ 0.05) compared to RW, and the viscera-somatic index (VSI) was significantly lower in GIANT cultured in IPRS correlating with reduced fat content, and there were no significant differences in any parameters measured on diets. In addition, total biomass showed higher (<i>P</i> ≤ 0.05) with GIANT in IPRS system about 689.78 kg/ha, and net yield was 2.20 kg/m³ compared to the Kafr El Sheikh strain. Moreover, Fillet yield increased 8.5% by IPRS-reared GIANT compared to RW systems. This study demonstrates that GIANT Abbassa strain cultured in IPRS outperforms in growth, yield, and fillet quality providing a sustainable model for intensifying tilapia aquaculture.</p></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"33 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10499-025-01920-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research introduces a novel approach to RAS feeding control using a Deep Deterministic Policy Gradient (DDPG) reinforcement learning algorithm. The developed system integrates feeding rate optimization with comprehensive water quality management to improve overall performance and stability. The DDPG controller demonstrated superior tracking accuracy, reduced feed consumption, and improved operational stability compared to traditional control methods such as Model Predictive Control (MPC), PID, and Bang-Bang control. The learned policy-maintained feeding rates within optimal ranges while adapting to dynamic system requirements and environmental conditions. The integration of water quality monitoring and control further enhanced system stability, ensuring critical parameters remained within target ranges. Comparative analysis revealed the DDPG controller’s advantages in terms of faster recovery times after environmental perturbations, improved long-term stability, and significant economic benefits through reduced operational costs and increased efficiency. The robustness and adaptability of the system were validated through comprehensive testing under various fault conditions, growth phases, and system scales. The successful development and evaluation of the DDPG-based RAS feeding control system represents a significant advancement in aquaculture management. The demonstrated improvements in efficiency, stability, and economic performance establish the potential for this approach to revolutionize feeding practices in commercial RAS operations. Further research and development efforts can build upon these findings to advance the state-of-the-art in intelligent aquaculture management systems and promote the sustainability and profitability of the industry.\u0000</p></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"33 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10499-025-01914-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
